High-rise buildings have recently increased over the residential, commercial and office facilities, thus an understanding of construction cost for high-rise building projects has been a fundamental issue due to enormous construction cost as well as unpredictable market conditions and fluctuations in the rate of inflation by long-term construction periods of high-rise projects. Especially, recent violent fluctuations of construction material prices add to problems in construction cost forecasting. This research, therefore, develops a time-series model with the Box-Jenkins methodologies and material prices time-series data in Korea in order to forecast future trends of unit prices of required materials. BIM (Building Information Modeling) approaches are also used to analyze injection time of construction resources and to conduct quantity takeoff so that total material price can be forecasted. Comparative analysis of Predictability of tentative ARIMA (Autoregressive Integrated Moving Average) models was conducted to determine optimal time-series model for forecasting future price trends. Proposed BIM based time series forecasting model can help to deal with sudden changes in economic conditions by estimating future material prices.

The flavor constituents and functionality of small kingfish were studied as affected by two stage enzyme hydrolysis (TSEH). Total free amino acid contents in water extract, autolytic extract and TSEH of small kingfish were 541.3 mg%, 8,245.3 mg% and 6,636.6 mg%, respectively. Major free amino acids in TSEH were hydroxyproline, glutamic acid, proline, leucine, phenylalanine, lysine, arginine. As for nucleotides and other bases, IMP, TMAO and total creatinine were principal components in TSEH. And the major inorganic ions in TSEH were Na, K, P, Cl and $PO_{4}$. Also TSEH of small kingfish revealed very higher Angiotensin-I converting enzyme inhibition effect than those of water and autolytic extract.

Unusual precipitation caused by typhoons and severe rain stormscan threaten human life and property. Thus, various organizations prepare emergency action plans (EAPs) to provide proper guidelines for operators, experts, and emergency response personnel to protect and enhance critical infrastructure. For example, FEMA and DHS have various types of EAPs for dams, levees, and other structures to protect people and property. FEMA defines EAPs as official documents to decrease the damage and impact in emergency situations and to reduce casualties. These documents should consider all possible situations in an emergency and can reduce problems in facility management. This study analyzes EAPs for infrastructure from the USA, Japan, and Korea in order to suggest an ideal EAP framework. EAPcontent can include how to guide experts and operators in disaster stages (mitigation, preparedness, response, and recovery), how to operate emergency equipment, and how to protect critical infrastructure and life. The suggested EAP framework performed very well in a test location. It can therefore be used for infrastructure organizations in Korea and to inform of the appropriate processes and methods for risk reduction in flood disasters.

Soybean (Glycine max (L.) Merr.) seed is the main source of protein and oil for human and animal. The use of soybean protein has been expanded in the food industry due to their excellent nutritional benefits. But, antinutritional and allergenic factors are exist in the raw mature soybean. Lipoxygenase, Kunitz trypsin inhibitor (KTI) protein, and ${\alpha}^{\prime}-subunit$ of 7S globulin are main antinutritional factors in soybean seed. Breeding of a new soybean strain with lacking these components is needed. The objective of this research was to select new soybean line with lipoxygenase-free, KTI-free, and ${\alpha}^{\prime}-subunit$ free (lx1lx1lx2lx2lx3lx3titicgy1cgy1 genotype). Total 434 $F_2$seeds were obtained from the cross of cultivar, "Gaechuck#2" and PI506876. Presence and absence of lipoxygenase, KTI protein, and ${\alpha}^{\prime}-subunit$ of 7S globulin was tested by SDS electrophoresis using a partial seed of each $F_2$seed. Only one $F_2$seed with lacking these three components was selected and was planted to $F_2$plant. Absence of lipoxygenase, KTI, and ${\alpha}^{\prime}-subunit$ protein was confirmed on the $F_3$seeds harvested. Selected line with lx1lx1lx2lx2lx3lx3titicgy1cgy1 genotype might be useful for soybean breeding.

The purpose of this study is to analyze the current status of counter terrorism system and to identify the causes of problems and to suggest alternatives by selecting legal and operational sectors based on theories of open systems and integrated systems. According to the results of the research, first, the degree of agreement on the open system and the integrated system is low with regard to the characteristics of the counter-terrorism system. Second, in relation to the importance and necessity of major factors of construction and operation of counter-terrorism system, counter-terrorism workers recognize that it is the most important and necessary. In the case of strengthening international cooperative system, the difference of recognition between importance and necessity was the biggest. The importance and necessity of reviewing the Anti-Terrorism Act for the protection of the public and public safety were relatively low, and the cooperation with the private sector showed the lowest importance and necessity. In the case of academic achievement, the average level of high school graduates is higher than that of professional high school graduates. Therefore, this research concludes that counter terrorism operation system with open and integrated system has to be applied to national counter terrorism operation structure in South Korea in increasing the quality and efficiency of nation counter terrorism response capability.

This study is for the use of color recommendation system for the color combination of mobile application. For this study, color combination methods of a material design color system that recommends harmonized colors automatically and of a mobile web application were applied to a mobile application design and a color combination experiment was carried out. Then for a survey on the experiment using the two methods, color combinations, selected colors and satisfaction with outputs were investigated on a 7-point Likert scale. And color combination characteristics of outputs were compared. It was found that the material design color palette made it easy to select colors by systematizing the regular coloring stages of fixed colors automatically, but there were differences in color compositions and color scopes of dominant color, assort color and accent colors, which are three-color combinations of mobile web application and accent color selection function was required for each design, since only primary colors and secondary colors could be selected. Moreover, chromatic colors were used a lot in the material system because of the fixed color scopes and color combination scopes and images of color combination outcomes varied depending on the color combination scopes, even when tones with a big contrast or complementary colors were selected. The role of color composition was important according to the color combination scopes.

This study aimed to develop a group rap making program and examine its applicability to improve communication skills of adolescents with mild intellectual disabilities (ID). Three adolescents with ID participated in a total of six 50-minute group sessions over 4 weeks. The group rap making program included three stages: understanding the context of communication, learning how to communicate with others, and applying the communicative behaviors in a group setting. To examine changes in the participants' communication skills, the rap lyrics constructed by participants were analyzed and communicative behaviors were observed during sessions and analyzed in terms of asking questions and providing information to others. Also, a social communication skills checklist was rated by the participant's caregivers. The analysis of rap lyrics showed that the expressions included in the rap were diversified as the session proceeded. Changes in observed behaviors supported that participants became to engage in communication with others more actively in order to complete the group rap. While the social communication skills checklist tended to increase, there was a difference in degree of change depending on the level of language communication skills. These results indicate that a group rap making can be an effective option for these adolescents to learn how to communicate with their peers, which presents implications for how rap making can be used for therapeutic purpose with more diversified population.

The purpose of this study was to investigate the single-person household's demand for a wearable healthcare system that provides the ischemic heart disease and cardiopulmonary alarm to be developed. In this study, in-depth interviews were conducted with six unmarried individuals in their thirties who were in the workplace and the results were interpreted by Giorgi's phenomenological analysis method. The study results indicated that although the wearable healthcare system was implemented with high-technology functions that serve the intended purpose, it is necessary to comprehensively consider factors such as aesthetics, comfort, and ease of washing. In this study, we found that the variables influencing the interviewees' intent to accept healthcare services are complex and cannot be attributed to one factor alone; this study has also shown a variety of interpersonal correlations. In addition, although health-care research focusing on the elderly has been conducted in the past, it is suggested that younger generations such as those in their thirties can also be studied as health care service adopters.

Future prospects for the North Korean construction market created by reunification of the Korean Peninsula has consistently been recognized as highly promising. Although rehabilitation projects of the deteriorating construction facilities in North Korea are expected to serve as new source of growth engine to South Korea in future, the status quo of each infrastructure in the North are described verbosely with signs of subjective translation. There has been limited approach on depicting the condition and performance of the North Korean facilities based on quantitative and systematic approach. Thus, this study has been conducted under a twofold purpose. First, this study proposes a performance indicator for identifying the status quo of the major construction facilities in North Korea based on a quantitative approach. Second, this study applies the developed indicator to visualize the results on the conditions of each facility in the form of a report card. This expected to serve as a basis on determining the appropriate level of the construction infrastructure in North Korea and estimating the range of rehabilitation projects along with the investment cost.
